In From Slavery to Freedom in Brazi, Bahia 1835-1900, Dale Torston Graden writes in an aside about changes in pro-slavery rhetoric “in the wake of the February 1848 publication of the Communist Manifesto in London. The book was viewed as an evil doctrine by many in Brazil. Communism was considered as a threat to the right to own private property and to entrepreneurship in a free market. Not surprisingly, conservative defenders of the status quo in Brazil used the word to besmirch antislavery proponents from the late 1860s on.” (117.)
